Mario Boriello appears as a catalogue artist-name form in Francesco Molinari-Pradelli’s stereo recording of Puccini’s Manon Lescaut with Renata Tebaldi.

The catalogue also contains the related spelling Mario Borriello, attached to Callas’s Turandot. The available product evidence suggests a spelling variation, but this entry is kept cautious.

Because wider public biographical detail is limited, this page acts mainly as a spelling-form marker.

It keeps the Tebaldi Puccini strand navigable without forcing an uncertain identity beyond the tag evidence.
